A lot of effort and money is being expended on aircraft propulsion involving batteries when the fundamental weight problem is a very long way from solution, if it ever can be solved ("Flights of fancy?" Professional Engineering No 5).
He said that he's a Trekkie and that about a decade ago, when he began pondering new forms of aircraft propulsion, he imagined that in the future there should be "planes that fly silently with no moving parts."
Orbital ATK has entered into a contract with the Defense Advanced Research Projects Agency to study potential integration of turbine and hypersonic engine technologies into a new aircraft propulsion system under DARPA's Advanced Full Range Engine program.
Mr Parkinson also previously held a number of manufacturing and operational management roles at Intel's IC fabrication plant in Ireland after serving twelve years as an aircraft propulsion systems engineer with the Royal Air Force.
